SH-250 МГц256 КБ (256К x 8)

Overview

OverviewThe SH7144 Group and SH7145 Group single-chip RISC (Reduced Instruction Set Computer) microcomputers integrate a Renesas Technology original RISC CPU core with peripheral functions required for system configuration.The SH7144 Group and SH7145 Group CPU has a RISC-type instruction set. Most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. In addition, the 32-bit internal-bus architecture enhances data processing power. With this CPU, it has become possible to assemble low cost, high performance/high-functioning systems, even for applications that were previously impossible with microcomputers, such as realtime control, which demands high speeds.

• Central processing unit with an internal 32-bit RISC (Reduced Instruction Set Computer) architecture⎯ Instruction length: 16-bit fixed length for improved code efficiency⎯ Load-store architecture (basic operations are executed between registers)⎯ Sixteen 32-bit general registers⎯ Five-stage pipeline⎯ On-chip multiplier: multiplication operations (32 bits × 32 bits → 64 bits) executed in two to four cycles⎯ C language-oriented 62 basic instructions• Various peripheral functions⎯ Direct memory access controller (DMAC)⎯ Data transfer controller (DTC)⎯ Multifunction timer/pulse unit (MTU)⎯ Compare match timer (CMT)⎯ Watchdog timer (WDT)⎯ Asynchronous or clocked synchronous serial communication interface (SCI)⎯ I2C bus interface (IIC)*1⎯ 10-bit A/D converter⎯ Clock pulse generator⎯ User break controller (UBC)⎯ User debugging interface (H-UDI)*2⎯ Advanced user debugger (AUD)*2
